+# Rate music for Raspberry Pi Pico
+
+This is the MicroPython project to connect the Raspberry Pi Pico to the rate_music database via HTTP.
+
+## Installation
+1. Follow the [instructions](https://www.raspberrypi.com/documentation/microcontrollers/micropython.html) to install MicroPython on the Raspberry Pi Pico.
+2. Install [rshell](https://github.com/dhylands/rshell).
+3. Modify `SSID` and `Password` in the `main.py` file.
+4. Copy the files `main.py, rate.py, wifi_client.py` to the Pi Pico.
